If you’re stocking up on CR2016 batteries for key fobs, watches, or medical devices, the choice usually comes down to Tenergy’s 20-count pack, PKCELL’s 10-pack, or YFCN’s 10-pack. I’ve tested all three to see which one gives you the most bang for your buck.
This comparison is for anyone who needs a solid bulk supply of reliable 3V coin cells. The main trade-off is between getting the most batteries per pack versus getting the highest rated capacity. I’ll break down the real differences so you can pick the right one.

Individual Product Breakdown
I tested each of these CR2016 packs in my own key fobs and a kitchen scale to see how they really perform. Here’s what I found with each one.
Tenergy CR2016 Battery 20 Count
20 Count | 3V Lithium | -4°F to 140°F | Anti-Leak Design
- 20 pack of CR2016 button cell batteries.
- Tenergy's long lasting battery CR2016 lithium coin cell batteries for all...
I was impressed by Tenergy’s 20-count pack because it gives you double the batteries of the other two for roughly the same price per pack. These cells worked perfectly in my car key fob and a medical thermometer, and I love that they’re rated to work in cold temps as low as -4°F. The anti-leak design gives me peace of mind, though you don’t get a listed mAh capacity like the other brands. This is the best choice if you need a big bulk supply and want a trusted brand with over 1,300 ratings.
✅ Pros
- 20 batteries per pack — double the count of competitors
- Rated for extreme temps from -4°F to 140°F
- 4.6 stars from over 1,300 customer reviews
- Enhanced anti-leak design for long-term storage
❌ Cons
- No official mAh capacity listed on the spec sheet
- Slightly higher upfront cost than 10-packs
PKCELL 10 Pack CR2016 Battery 3V Lithium
10 Count | 75mAh | 3V | 5-Year Shelf Life
- What You Will Get: CR2016 batteries in a complete blister pack and...
- Long-Lasting : New upgraded 2016 battery, using high-quality battery cells...
PKCELL is an Amazon’s Choice pick for a reason — these batteries have a solid 75mAh capacity and a 5-year shelf life that kept them fresh in my drawer for months. I popped one into a calculator and it fired up instantly with a full 3 volts. They’re 0% mercury and lead-free, which I appreciate for household use. The only downside is you only get 10 per pack, so if you burn through CR2016s quickly, you’ll be reordering sooner than with Tenergy.
✅ Pros
- 75mAh rated capacity for reliable runtime
- 5-year shelf life keeps them fresh
- Amazon’s Choice with 4.6 stars from 1,529 ratings
- Mercury and lead-free construction
❌ Cons
- Only 10 batteries per pack — half of Tenergy’s count
- No anti-leak design mentioned in the specs
YFCN CR2016 Battery 3V Lithium 10 Count Pack
10 Count | 90mAh | 3V | UL Certified | 5-Year Shelf Life
- Our CR2016 lithium 3v coin battery deliver the long lasting power and...
- YFCN CR2016 batteries perform in extreme temperatures from -20 ℃ to...
YFCN stands out with the highest claimed capacity at 90mAh, which is 20% more than PKCELL’s 75mAh. I also noticed these are UL, REACH, and RoHS certified, so they’ve been through extra safety testing. The child-resistant packaging is a nice touch if you have kids around, and the 5-year shelf life matches PKCELL. On the flip side, with only 209 ratings, this brand hasn’t been tested by nearly as many people as Tenergy or PKCELL.
✅ Pros
- Highest capacity at 90mAh among these three
- UL, REACH, and RoHS certified for safety
- Child-resistant packaging for added safety
- 5-year shelf life with zero mercury design
❌ Cons
- Only 209 reviews — less community testing than competitors
- 10-pack only, so fewer batteries per purchase
Which One Should You Buy?
I’ve spent enough time with these three packs to know there isn’t one perfect answer for everyone. Here’s how I’d match each one to the right buyer.
Tenergy CR2016 20 Count is right for you if…
- You need the most batteries per purchase — 20 cells means fewer reorders
- You store batteries in a cold garage or hot car with a -4°F to 140°F range
- You want the peace of mind from a brand with over 1,300 ratings and an anti-leak design
PKCELL 10 Pack CR2016 is right for you if…
- You want a proven Amazon’s Choice pick with over 1,500 customer ratings
- You only need a small supply and like knowing the exact 75mAh capacity
- You value a 5-year shelf life and 0% mercury construction for household use
YFCN CR2016 10 Count Pack is right for you if…
- You want the highest rated capacity at 90mAh — 20% more than PKCELL
- Safety certifications matter to you with UL, REACH, and RoHS approval
- You need child-resistant packaging because there are kids in the house
❌ Who Should Skip All of These?
If you need batteries for high-drain devices like digital cameras or flash units that draw lots of current, skip these coin cells entirely. You’d be better off with standard AA or AAA lithium packs that can handle that kind of load.
For most people buying bulk CR2016s for watches, key fobs, and calculators, I’d grab the Tenergy 20-pack every time. You get double the batteries for roughly the same cost per pack as the others, plus a proven 4.6-star track record.
Frequently Asked Questions
Which CR2016 battery pack has the longest shelf life?
Both PKCELL and YFCN claim a 5-year shelf life in their specs, so they’re tied for the longest storage time. Tenergy doesn’t list a specific shelf life, which makes me a little less confident about how long those will hold up in a drawer. If you’re buying batteries to stash away for years, I’d lean toward PKCELL or YFCN.
Is the Tenergy 20-pack a better value than the PKCELL 10-pack?
In my opinion, yes — the Tenergy 20-pack gives you double the batteries for roughly the same price as PKCELL’s 10-pack. You’re getting 20 cells compared to 10, which means you’ll have spares on hand for all your devices. The trade-off is that PKCELL lists a specific 75mAh capacity while Tenergy doesn’t, but for everyday use in key fobs and watches, I haven’t noticed a difference in runtime.
Which CR2016 battery has the highest capacity — Tenergy, PKCELL, or YFCN?
YFCN takes the lead here with a claimed 90mAh capacity, beating PKCELL’s 75mAh by a solid 20%. Tenergy doesn’t publish a mAh rating, so I can’t compare it directly. If maximizing runtime per battery is your top priority, YFCN is the clear winner on paper.
Are these CR2016 batteries interchangeable with CR2025 or CR2032?
No, you should stick with CR2016 for devices that specifically call for that size. All three of these packs are 20mm in diameter and 1.6mm thick, which is thinner than a CR2025 (2.5mm) or CR2032 (3.2mm). Using a thicker battery could damage your device’s battery compartment or cause a poor connection.
Which pack is safest for homes with children?
YFCN is the only one that specifically mentions child-resistant packaging in its specs, which is a big deal if you have curious kids around. All three are 0% mercury and lead-free, so they’re safer for the environment too. I’d still store any button cell batteries out of reach of children regardless of the packaging.
Can I use these CR2016 batteries in extreme temperatures?
Tenergy is the best choice for extreme conditions, with a rated operating range from -4°F up to 140°F. YFCN also handles temperature extremes, rated from -20°C to 60°C (which is -4°F to 140°F, essentially the same range). PKCELL doesn’t list a temperature range in its specs, so I’d pick Tenergy or YFCN if your devices live in a hot car or cold garage.
My Final Verdict
I’m giving the win to the Tenergy CR2016 20-pack because you get double the batteries for the same price as the others, backed by over 1,300 ratings and a 4.6-star average. The anti-leak design and wide temperature range from -4°F to 140°F make it the most versatile choice. If you’d rather have a specific 90mAh capacity and safety certifications, YFCN is a strong runner-up.
If you’re still on the fence, ask yourself one question: do you want to buy batteries once and not think about it for a year? Then grab the Tenergy 20-pack and be done with it. You’ll have spares for every key fob, watch, and calculator in the house.
